Global Hydropower Day on 11 October 2026 will celebrate the positive impacts of sustainable hydropower on people and communities around the world.

Spearheaded by the International Hydropower Association (IHA), with support from a coalition of developers, operators, manufacturers and industry associations around the world, this day will shine a light on the power that can be harnessed with sustainable hydropower.

Hydropower is the oldest form of renewable energy and has a key role to play alongside all forms of clean energy to push the world towards a net zero future.

Various videos, case studies, stories and more will be represented throughout the day, covering what can be achieved #WithHydropower.
